Patented il. 1933 'UNITEDy STATES PATENT OFFICE 1,920,732 sPmNING oEN'r'mFUGE Waldemar Zur Lwen, Wuppertal-Barmen, Germany, assignor to American Bemberg Corporation, New York, N. Y., a Corporation of Dela- Ware 6 Claims.

This invention relates to the manufacture of artiiicial silk and the like, and more particularlyA to the manufacture of artificial thread by the pot spinning process.

In the manufacture of artificial thread and the like by the above process, the thread is led from the precipitating bath to a suitable spinning pot. Heretofore the spinning pot has been so journalled as to be rotated and at the same time raised and lowered so that the thread, coming from the iixed guide tubevmay be laid evenly on the inner wall of the spinning pot. Such mechanism has been found to be cumbersome and inefficient due to the complicated mechanism necessary to impart the desired rotary and reciprocating motion to the spinning pot.

This mode of operation has been abandoned and the thread guide tubes have been' reciprocated instead of the spinning pot which has been journalled so as only rotary motion is imparted thereto. These thread guide tubes are secured to bars which are Areciprocated by a cam drive through a common rocking shaft. As the motion is imparted from a main drive/to a number of lament guiding tubes the transmission gearing is necessarily complicated.

The invention hereinafter described constitues a divisional application of Waldemar` Zur Loewen, iiled August 11, 1931; Serial Number 556,428. In that application mechanism is described whereby each filament guiding tube has an independent drive thus reducing the number of operative parts and rendering the operation of the machine more eiiicient.

It is an object of this inventionto provide suitable housing 'for the spinning pot whereby motors of different sizes may be used without necessitating a'change in the driving mechanism for the thread guide tube.

Another object o! this invention is to provide a suitable housing for .the spinning pot mechanism whereby the spinning systems now in use may be readily changed over to individual drives.

These and other objects of this invention will become more apparent from a study of the following description and the attached drawing in which the ligure is a view of a spinning centrifuge mechanism enclosed `in al suitable housing.

The spinning pot 10, which is enclosed in a Vhousing 11, is driven through any suitable detachable, connection by an electric motor 12. 'I'he motor is suspended in the housing by meansof supports or brackets 1,3, and is separated from the spinning pot or centrifuge by-the partition 14. The brackets are provided 'with r 15 in which are located rubber cushions or gaskets 16 and upon which the upper rim 17 of the motor rests. To accommodate various sizes of motors I a plurality of different lsized supports or brackets 13 are provided.

Located on the bottom of the housing 11 is the housing 18 for the'thread` guide tube reciproeating mechanism. A shaft 19 is suitably journalled in the housing and projects therethrough directly below the motor. A iiexible connection 20 is provided between the Ishaft and motor. A gear 21 secured to the shaft is adapted to drive the reduction gearing 22, cam drum 23, and thread guide rod 24, thereby imparting a reciprocating motion to the thread guide tube 25. The thread guide rod reciprocates in the 'bearing provided-by the conduit 30. As may be clearly seen the driving mechanism encased in the housing 18 is completely immersed in the oil contained therein.

The electrical energy necessary to drive the motor supplied through the plug 26 located in the bottom of the housing. The current is taken off through a cable 27 by means of a switch 28 actuated by the lever 29.

In operation the motor is started, rotating the spinning pot or centrifuge against the inner walls of which the thread is being placed. The thread guide tube is reciprocated, to insure the formation '-of a substantially even layer of thread, by the motor through the flexible connection reduction gearing, cam drum and thread guide rod.

.From the above. description it will be appreciated that there has been provided a simple and eilicient means for providing each spinning pot or centrifuge and thread guide means with an individual drive thereby rducing the cost of operation and maintenance.

Although this invention has been described with reference to a specific embodiment thereof,

it will be readily vappreciated that the device is susceptible of many variations in the construction thereof without departing from the scope of the invention or claims.
